Patented June 25, 1907 Application martin 27,1907. Serial No. 370,669.

I Trucks, of which'the following is a full, clear,

and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in /which truck showing Figure l is a side elevational' view 'of a car aside frame constructed in accordance -with my invention; Fig. 2 is a cross sectional view of the side frame; and

- Fig. 3 is a perspective view shbwin a bolster which is intended a be use (l with proved sideframe. 1

This invention relates to car trucks, and articularly to that typein which the side rames consist of a one-piece casting.

The main object of my i vention is to providea 'cast metal side frame which is so conmy imstructed that it permits the use of a bolster of standard type,' and enables the bolster to be ujtfin place and removed easily. I,

ignnther object is to rovide-a castside frame rovided Withan't'opening to'receive .theen f'nf, a. bolster, said oplening being so forn iedthat the bolster/can e inserted ma vertical position and'thereafter rotatedin a horizontal position and moved upwardly so that its column guides will umns of the side frame.

The standard bolster which is now in general use, is .providedion its sides with integral laterally projecting column guides, and between said guides the side faces of the bolster' are perfectly flat so as to provide an extended bearing surface between the bolster and the columns of the side'frames of the truck. The distance betweenthe inside faces of the columns must corres 0nd to the width of that portion of the b0 ster which lies between the'columns, and as the column guidesproject laterally beyond the sides of the bolster theonly Way in which the bolster embrace the colthe co umns and then turn 1t into a horizontal' position so that its column guides will embrace the columns of the side frames, M improved side frame is so formed that the rotatinggr turning of a standard type bolster is permitted in placing it in an operative position.

Referring to the drawings which illustrate the preferred form of my invention, 1 desig nates one of the side frames of a car truck. This side frame consists of a one-piece casting, preferably of steel, and provided with an opening 2 of sufficient depth to receive the end of the bolster 3- when it is arranged in a vertical position. The columns 4 which form the sides of said 0 ening are rovided on their inner sides wit integral fanges 5, and the distance between the'uppe'r ends of these columns at the point where the bolster is located-when in operative position, corresponds to the width of the bolster so the.v 'tln sides of the bolster will bear firmly against the insidev flanges of the columns.

At approximately the middle's of the columns are curved ortions 6, the distance between the curve portions of the two columns being greater than the distance between the upper ends of the columns so that the bolster can be-turned from a vertical position into a' horizontal osition and then moved upwardly to cause its integral column uides 7 to embrace the columns of the side which the bolster rests, the s1de frames also being provided with lateral projections 10 I that are arranged between the angles '8 to form parts of the spring seats.

l Having thus described my inventionl what I claim as. new and "desire to secure 'bif Let ters Pat ent is: Q l

1. A-car truck side frame royided with an openin to receive the end 0 a bolster having ntegra column guides, said frame compris mg columns 'WlllCll have curved portions 1ntermediate their ends that ermit the bolster. to be turned from a vertica into a horizontal position; substantially as described. 1 ,2.'A car truck side frame consisting of a casting that-is rovided with an opening-to receive the en of a bolster, and columns forming the sides'ofsaid opening and provided at approximately their centers with curved portionsj substantially as described.

3. A car truck side frame consisting of a casting having an opening to receive the end of a bolster, portions of the side wallsol' said opening being curved to permit the bolster to be turned from a vertical into a horizontal position; substantiall as described.

4. A car truck side frame consisting ol" a one-piece casting that is provided with an opening to receive the end of a bolster and with flanges forming the side walls of said opening, said side walls having curved portions that permit the bolster to be turned from a vertical into a horizontal position; substantially as described.

5. In a car truck, a side frame provided with an opening to receive the end of a bolster, said opening being so formed that the bolster can be inserted in a verti ial position and thereafter turned into a horizontal position, and a bolster arranged in said opening and provided with laterally projecting column guides and flat side faces between said guides; substantially as described.

6. In a car truck, a side frame provided with an opening to receive the end of a bolster, and a bolster arranged in said opening and provided with laterally projecting column guides, a portion of said opening corresponding to the width of said bolster, and a portion of said opening being of greater width than the bolster to permit it to be turned. from a vertical into a horizontal position substantially as described.

7. In a car truck, a side frame comprising a casting that is provided with an opening to receive the end of a bolster, and a bolster arranged in said opening and provided with laterally projecting column guides,portions of the side walls of said opening being curved to permit the bolster to be turned from a vertical into a horizi'mtal position; substantiall as described 8'. .ln a car truck, a side frame comprising a casting provided with columns having curved portions, a bolster arranged between said columns above the curved portions thereof. and guides on saidbolster which em brace the columns of the side frames: sub stantiallv as described.

J. ln a car truck. a side frame having olumns provided on their inner sides with flanges, said columns having curved port ions intermediate their ends, and a bolster arranged between said columns and provided with laterally projecting column guides that embrace the columns of the side frames and flat side faces that bear against the flanges on the insides of said columns; substantially as described.

It). In a car truck, a side frame provided with an opening to receive the end of a bolster and flanges "forming the sides of said opening, and a bolsterprovided with column guides and with flat side faces between said guides, said bolster being adapted to be inserted edgewise in the opening in the side frame, and tlw eafter turned to cause its column guides embrace the flanges on the side frame; substantially as described.

1]. In a an truck, side frames provided with openings to receive the ends of a bolster and flanges forming the sides of said openings, a bolster provided with column guides and with flat faces between said guides, said bolster being adapted to be inserted edgewise in the-openings in the side frames and thereafter turned to cause its columnguides to embiace the flanges on the side frames, a spring plank. and s nings inter )osed between the spring planii and the bolster; substantiall as described.
